Abstract

Most wearable system for mobile healthcare applications consists of three parts. The first part is the sensing elements based on bio-signal, the second is the circuit module for control, data acquisition and wireless communication and control and the third is garment with a built-in electrodes and circuits. The existing healthcare garment systems have to find a solution to signal-wire and uncomfortable and inappropriate electrode to long-term attachment. Even if the wireless communication is used for healthcare garment system, the interface between sensors and circuits have to use wires. To solve these problems, this paper use electrode using PEDOT coated PVDF nanoweb for ECG signal and PVDF film sensor for respiratory signal. And, we constructed garment network using digital yarn of 10um, and transmitted ECG and respiratory signal to mobile phone through the integrated circuit with bluetooth called station To evaluate feasibility of the proposed mobile healthcare garment system, we experimented with transmission and measurement of ECG and respiratory signal using nanoweb electrode and digital yarn. We got a successful result without noise and attenuation.

대부분의 모바일 웨어러블 헬스케어 모니터링 의류 시스템은 생체신호를 측정할 수 있는 센서와 데이터 취득과 무선 통신 및 제어를 담당하는 회로부, 이들을 내장하는 의복으로 구성된다. 기존의 의복형 헬스케어 시스템은 센서를 의복에 장시간 내장하기가 어렵고, 피부 접촉 시 시간에 따라 저항 값이 변화하기 때문에 장기적인 생체 신호 모니터링이 쉽지 않으며, 센서 전극과 회로 사이에 존재하는 신호선의 물리적 장애 요인도 가지고 있다. 본 연구에서는 이러한 문제점들을 해결하기 위하여, PVDF에 PEDOT 재료를 코팅하여 만든 패브릭 나노웹 ECG 전극과 PVDF 필름을 사용한 호흡 센서를 $10\;{\mu}m$ 두께의 디지털 실을 이용하여 사용자의 의류와 일체화하였다. 탈부착이 가능한 무선 블루투스(Bluetooth) 내장 스테이션과 디지털실로 기존 의류와 일체화한 생체 신호 측정용 의류 제작을 통해, 휴대폰에서 손쉽게 심전도(ECG)와 맥박신호를 표시 할 수 있었다.
